Abstract

The v = 2/3 fractional quantum Hall effect (FQHE) in a wide, single quantum well subject to tilted magnetic fields makes a one-component to two-component transition induced by the in-plane component of the magnetic field. To analyze the experimental data we make a self-consistent, local-density-approximation calculation of the electronic structure of the wide quantum well in tilted magnetic fields. Our results are quantitatively consistent with the earlier experimental work on the density driven one-component to two-component FQHE transition in this system.
